Water Jet Urine Supernatant Aspirator

Abstract

Nowadays, the urine supernatant aspirators for urinalysis are all electric devices. Some needs  reservoir tank, which requires decantation when it is full. An in-house urine aspirator is designed by using only pipette tip, plastic tubes and tap water which are available in any laboratory or a hardware store. By using basic principle of water replacement, to generate vacuum force for this device, then the supernatant of the urine can be aspirated out easily. Hence, the supernatant fluid will be suctioned out directly to the sewage pipeline while the remaining volume of urine is fixed with a pre-calibrated disc. This in-house urine aspirator is easy to use while increases accuracy and precision of the urine sediment preparation with limited direct contact and bad odor.
